UNITED sTATEs PATENT oEErcE WATER-NOZZLE.

To all whom it may concern:

Be it known that we, ABRAM ALLBRTGHT and GEORGE G. SCUDDER, citizens of the United States, residing at New York city, county and State of New York, and Babylon, county of Suffolk, State of New York, respectively, have invented certain new and useful Improvements in Tater-Nozzles, of which the following is a full, clear, and exact description.

@ur invention relates to improved nozzles for directing and controlling` the throw of water.

The object of the invention is to provide a simple, effective and durable nozzle construction of particular value for so-called high pressure service, the arrangement being such that the stream may be controlled and modified within a wide range.

in the accompanying drawing Figure 1 is in the main a longitudinal sectional view of our improved nozzle, in one preferred form. Fig. 2 is a cross section on the line r-m Fig. 1. Fig. 3 is a cross section on the line g/-y Fig. 1.

1 is the base of the nozzle, of tubular form, provided with a suitable means at its rear to permit a hose or water pipe to be connected thereto, the particular form of this connecting means being entirely immaterial.

2 is a screw-thread around the body 1, mounted upon which thread is a valve-controlling handle 3. This handle 3 may be moved back and fort-h by rotation upon the screw-thread 2.

4 is an outlet nozzle of the given diameter and tapered in the usual manner. 5 is a second outlet nozzle of larger diameter and spaced apart from the nozzle 4. This nozzle 5 is likewise tapered and may be tted with a suitable tip outlet 6, whereby the diameter of the outlet proper may be varied by sub` stituting tips of different sizes. The tubular body 1 and the nozzles 4 and 5 are concentric. The nozzles 4 and 5 are rigidly connected in any suitable manner, as by webs 7--7 8 8, which extend across the space between the outer wall of nozzle 4 and the inner wall of nozzle 5. The rear end of the nozzle 4 terminates forward of the forward end of the tubular body 1, and the space between said ends is bridged by an annular valve 9. The rear end of the nozzle 5 extends back around the outer wall of the forward end of Specification of Letters Patent.

the body 1 to form a housing space for the valve 9.

10 is a ring integral with the body 1 and affording a bearing support for the rear end of the nozzle 5. 11 is a second ring, which is preferably rigidly connected with the part 5 by a driving fit, and coperating with the ring 10 in forming a support and connection between the parts 5 and 1 when the nozzle is assembled ready for use. If desired, packing may be inserted between the parts 10 and 11.

12 is a threaded coupling screwed on to the rear end of nozzle 5 and arranged to take up against the ring 10, as shown, to lock the parts together.

14-14 are rods carried by a ring 15 and passing through the coupling 12 and rings lOll. These rods are carried to the rear end of the annular valve 9. The handle 3 makes operative connection with the ring 15, so that as said handle is moved to and fro, the valve 9, controlling the'space between the rear end of nozzle 4 and the forward end of tube 1, will be moved to and fro to close said space, or open the same to any desired extent. Zhen this space is closed, as shown in Fig. 1, water forced through the pipe 1 passes only through the nozzle 4 and out through its contracted forward end at the highest pressure and smallest bore. Hence, under these conditions for a given pressure at the source, a stream will be thrown the maximum distance. If it is desired to reduce the throw of the stream and increase the diameter' of the same, the operator merely turns back the handle 3 and withdraws the valve 9, whereupon a portion of the water passes out through the space thus opened and flows through the nozzle 5, mingling with the outgoing stream from the nozzle 4 at a lower pressure at the outlet. Under such conditions the throw of the stream will be shortened to any desired degree within a very wide range, the bore increasing as the throw decreases. 1

It is obvious that when water is flowing through the choke nozzle t, there is a greater back pressure than when water is flowing through both the nozzle t and the nozzle 5; hence it is possible, with a given pressure at the source of supply, to force a greater volume of water through both nozzles when cooperating than through the one nozzle t. This gives, therefore, to the improved nozzle a very wide range of flexibility and utility.

that we claim is:

l. In a nozzle, a main tubular body, two rigidly connected tapered nozzles arranged one within thepother and lia-ving an outlet in common, said nozzles being spaced apart at a point in front of said tubular body, a communicating passage near the base of the innermost nozzle leading to the space within the outermost nozzle, and a manually Aoperable valve for controlling said space said nozzle having a straight and unobstructed axial passage from end to end.

2. ln a nozzle, a main tubular body, two rigidly connected tapered nozzles arranged one within the other and having an outlet in common, said nozzles being spaced apart at a point in front of said tubular body, an annular comnninicating passage near the b ase of the innermost nozzle leading to the space within the -outermost nozzle, and a manually operable annular valve for controlling said space.

3. ln a nozzle, a main tubular body, two rigidly connected tapered nozzles arranged one within the other and having an outlet in common, said nozzles being spaced apart at a point in front of said tubular body, an annular communicating passage near the base of the innermost nozzle leading to the space within the outermost nozzle, and a manually operable annularl valve for controlling said space, `Said valve being longitudinally movable. y

4. ln a nozzle, a main tubular body, two nozzles of different diameters and arranged 'one within the other and snaced apart and 4having a common outlet, said nozzles being rigidly connected together, a communicating side passage from .the interior of the inside nozzle to the space within the outside nozzle, and a longitudinally movable manually operable valve for said passage.

5. ln a device of the character described, two nozzles of different diameters and arranged one `within the other and having' an outlet in common, web connections :tor rigidly holding said nozzles vagainst independent movement, an annular communicating passage leading irom the interior of the innermost nozzle to the space within the outermost nozzle, ,and a longitudinally movable annular valve for controlling said passage.

6. In a device of the character described, two outlet nozzles having outlets of different diameters and arranged one within the other, said nozzles being spaced apart, web connections between said nozzles,'means for conducting lluid to .the rear .ends or' :both of said nozzles, and means for cutting olf communication with the space around the innermost nozzle and .within the outermost nozzle comprising a longitudinally movable valve.
